Specification of Letters Patent.

Patented Oct. 15, 1907.

Application filed April 8,1907. Serial No. 366,771-

To all whom it may concern:

Be it known that I, Anrnun M. PADMORE, a citizen of the United States ofAmerica, residing at Chicago, in the county of Cool: and State ofIllinois, have invented new and useful Improvements in Davenports, of"which the following is a specification.

This invention relates to sofas of the davenport type, and particularlyto a convertible bed and sofa the ob- .ject in view being to provide aconstruction wherein the back and seat portions of the davenport may bedrawn out and adjusted to lie in the same plane to transform thedavenport into a bed, and wherein provision is made for facilitating andsecuring convenience in the adjustment of the parts and to afford readyaccess thereto for cleaning and repairs.

In the accompanying drawings,-Figure 1 is a vertical transverse sectionthrough the davenport with parts arranged to form a bed, as on line H ofFig. 3. Fig. 2 is a vertical front to rear section with the parts innormal position to form a sofa. Fig. 3 is a similar view, showing theseat and back sections adjusted to form a bed. Fig. 4 is a fragmentaryperspective view of one of the end portions of the main frame, showingthe guideways in the standards and the bottom thereof. Fig. 5 is asimilar view of the back and end frames, showing the same folded forconvenient storage or transportation. Fig. 6 is a view of one of thehingesprings. Fig. 7 is a view of one of the guide rods or bolts. Fig. 8is a detail illustrating the form and arrangement of the locking seatinthe longitudinal guide ways in the flame.

Referring to the drawings, the numeral 1 represents the main or bottomframe of the davenport, which is of oblong rectangular form andcomprises front and rear rails 2 and 3 and end rails 4, upon whichlatter are arranged track rails 5, the parts being connected and bracedin any preferred manner. To the rails a are secured the arms or sides 6,which may be of any desired form and construction, said sides or armshaving res-r extensions 7 constituting supporting posts or standards fora back-frame 8. The front and rear ends of the sides 6 terminate inshort depending legs 9 carrying casters 10. It will be understood thatthe back frame 8 may be of ornamental construction and serves to form ahead portion when the adjustable seat and back are drawn out to convertthe davenport into a bed.

I do not desire to restrict myself to the specific form of the sofa ordavenport shown, or to the specific shape or mode of constructing andconnecting any of the aforesaid parts thereof, as these may be modifiedso long as the frame structure is adapted to support the seat and backfor adjustability in the manner hereinafter described.

Each track rail 5 is provided with an outer longitudinal groovedguideway 11 and a shorter grooved inner guideway 12. The outer groovedguideways 11 of the two track rails receive guide rails or runners 13carried by the end rails of the frame 14 of the seat l5, which framecorresponds in form and dimensions with the main frame 1 and comprisesfront and rear rails 16 and 17 and end rails 18, the said front and rearrails being reinforced between the end rails by transverse bottom slats19. A joint-concealing strip 20 is provided upon the front rail 16 tolap over the front rail 2 of the frame 1 and conceal the joints betweenthem when the seat is in its normal position. The runners 13 project-inthe form of extensions 13 beyond the rear rail 17 to engage lockingseats or recesses 21 formed in the bottom wall of each guideway 11, fora purpose hereinafter described.

The frame- 22 of the back 23 corresponds in construction to the seatframe, and its parts are correspondingly numbered. These frames may beupholstered in any preferred style, and upon the front rail of the seatframe a pull-strapor handle 24 is provided to permit the same to beconveniently adjusted in a forward direction to convert the davenportinto a bed.

.Sccured to the under side of the frame 1 is a guard screen 25 toprevent the entrance of dust and vermin to the upholstered portions.

The davenport may be provided at the back or bemonth the bottom frame 1with a wardrobe box or compartment to receive the bedding. I have notshown this box or compartmnet, as the same does not form part of thepresent invention and may be constructed in any of the forms employed inconvertible sofas of this type.

At the lower or forward ends of the side rails of the back frame 22 areshort guide rails or runners 26 adapted to seat and slide in the innerguide grooves 12 in the track rails 5 in the back and forthadjustments'of the seat and back to form the sofa or bed. At the sidesof the upper end of the back frame are guide rods or bolts 27 of theconstruction shown in detail in Fig. 7, said bolts being arranged toproject and travel in guide grooves 28 formed in the standards 7. Theseguide grooves extend downwardly and forwardly on a. curved line from theupper rear ends of the standards to a point adjacent the rear ends ofthe track rails 5 and are provided at their lower ends with horizontalrear extensions or terminals 29. The rods or bolts engagingthese groovessupport the upper portion of the back in proper position and guide thesame in its adjustment. Each rod or bolt 27 is mounted to slide in alongitudinal casing 30 on a bracket plate 31 passing to the upper railof the frame and carries a knob or operating device 31, the stem ofwhich extends at right a-ngles thereto through a longitudinal slot 32 inthe easing, which slot is provided at its inner end with a. letersllocking offset 33- into which the stem may be turned to lock the rod orbolt in retracted position. A spring 34 is inclosed in the casingbetween the inner end wall thereof and the bolt and serves to hold thesame normally projected with its outer end seated in the groove 28, Uponretracting and locking both the bolts in retracted position the backframe will be released from engagement with the grooves 28 and may befolded downwardly over upon the seat frame 14, for the convenientremoval ofthese parts from the main frame.

The seat and back frames 14 and 22 are hingedly connected for movementin unison, the end rails of said frames carrying leavesv or hingemembers 35 and 36 pivotally connected at one end therewith, as at 37,and coupled at their opposite ends by a pintle pin 38, thus allowing theframe 22 to have free swinging movement on the frame 14 in its differentadjustments. The frames are also connected by poupling springsopera-ting both as hinges and means for facilitating the adjustment ofthe back to decrease the amount of power required in manipulating thesame. A pair of these coupling springs is employed and are attached tothe rear rail of the seat frame and the lower front rail of the backframe adjacent thesides of said frames. As shown in Figs. 5 and 6, eachof said hinge-springs is formed of a single piece of stout spring wire,the central portion of the wire being folded and twisted to form a mainattaching arm 38 provided with one or more eyes 39, the ends of the wirethence being bent to provide spring coils 40 and extended beyond thecoils to form opposing attaching arms 41. The arm 38 of each spring issecured by suitable fastenings passed through the eyes 39 to'the' rearrail of the frame 14, while the arms 41 are fastened to the lower railof the frame 22, thus disposing the spring coils 40 between the meetingends of the frames, the coils exerting pressure on the arms 41 tonormally swing them outwardly or away from the arm- 38.

Fig. 2 shows the parts in their normal positions to form adavenport-sofa, while Figs. 1 and 3 show the seat and back drawn out toconvert the sofa into a bed.

When an outward pull is exerted upon the strap 24, the seat will be slidoutward upon its runners 13 which travel in the guideways 11, and motionwill at the same time be communicated to the back, whose guide members.27 will travel downwardly and forwardly in the guideways 28, thuspermitting the back to swing outwardly and forwardly until its runners26 fit into the guideways l2 and said back assumes the position over themain frame 1 ordinarily occupied by the seatv 15, which latter willproject forwardly nearly its full width beyond said frame, theextensions 13 of its runners still, however, remaining in the forwardends I of the guide grooves 11 and holding the seat in position. It willbe observed that these extensions are long enough to project under theforward end of the back, so that the latter will bear thereon and thushold the seat from tilting'downwardly and outwardly. When the parts areadjusted to the stated positions, the guides 27 on the back will alinewith the horizontal grooves 29, thus allowing the seat and back to beslid rearwardly to the position shown in Fig. 3, whereby the normallyupper end of the back is permitted to extend to a position beneath theback-frame 8, allowing a greater portion of the seat to rest upon themain frame to secure a.

better support. In this operation the weight of the back causes thespring arms 41 to swing toward the arms 38 against the resistance of thecoils 40, by which the pressure of the springs will be utilized toassist in maintaining the back in a properly reclining position. Therunners 26 on the back sliding in the grooves 12 facilitate theadjustment of the parts, and it will be understood that when the seatand back are drawn forward to bring the guides 27 into the lower ends ofthe grooves 28 the parts may be restored to normal position by inwardpressure in which the rails 13 slide back in the grooves 11, while theguides 27 travel upwardly in the grooves 28, the runners 26 clearingormoving out of the guideways 12 in the upward swinging movement of theback. If desired this restoration of the parts to normal position may bemore conveniently accomplished by tilting the seat 15 upwardly until theextensions 13 of its runners bear at their rear ends against the bottomwalls of the grooves 11, whereby the forward end of the back will beelevated, thus lifting the runners 26 out of the grooves 12, enablingthe back to be shifted to normal position at a slight expense of energy.

The, amount of power required in this operation is decreased by the useof hinge-springs, which, as soon as the guides 27 reach the lower endsof the grooves 28, tend to expand and exert upward lifting pressure onthe seat. When the parts are in normal position the seat may be tiltedup. to a vertical plane and held in such position by engagement of therunner extensions 13 with the recesses 21, whereby the bottom of theseat frame will be exposed and the main frame 1 uncovered to permit theparts .to be more conveniently cleaned or repaired.

The mode of hingedly connecting the seat and back. frames permits thesame to be conveniently folded in parallel relation, as shown in Fig. 5,for convenience in storage and transportation. When'these parts are sofolded the arms of the springs lie in the same plane and the coils serveto maintain the frame in folded relation,

Having thus described the invention, what is claimed asnew, is: i

1. In a davenport-sofa-bed, the combination of a main frame havinglongitudinal and vertical guideways, the vertical guideways beingprovided with horizontal rear extensions at their lower ends, a seathaving runners to travel in the longitudinal guideways, and a backhinged to the seat at its normally lower end and provided at itsnormally upper end with guides to travel in the vertical guideways andtheir horizontal extensions,
